How Effective Are Horsefly Traps During Hunting Season?

May 8, 2026

Quick Answer

Horsefly traps can be moderately effective in reducing the number of horseflies during hunting season, but their effectiveness depends on various factors such as the type of trap, location, and the presence of other attractants.

Choosing the Right Trap

When selecting a horsefly trap for hunting, consider a UV light trap or a CO2 trap, as these are generally more effective than sticky traps or other types of traps. UV light traps can be particularly effective in areas with high horsefly activity, such as near standing water or in dense vegetation. For example, a UV light trap with a 365nm LED can attract horseflies from a distance of up to 100 feet.

Trap Placement and Maintenance

To maximize the effectiveness of horsefly traps, it’s essential to place them in areas where horseflies are most active, such as near trails or around bait stations. Regularly inspect and maintain the traps to ensure they continue to function properly. For example, replace the UV light in a UV light trap every 200 hours of operation to maintain its effectiveness. It’s also essential to clean and dispose of dead horseflies regularly to prevent the spread of disease.

Combining Traps with Other Methods

While horsefly traps can be an effective tool in reducing the number of horseflies, they should be used in conjunction with other methods to achieve optimal results. This can include using insect repellents, wearing protective clothing, and avoiding areas with high horsefly activity. For example, a combination of a UV light trap and a CO2 trap can be used to create a two-tiered defense system, drawing in horseflies and reducing their numbers in a given area.
